To treat water to make it safe to drink, disinfection processes are used in water treatment plants. These disinfection processes produce disinfection byproducts (DBPs) through the reaction of organic matter and the disinfectant, such as chlorine. DBPs have been shown to pose a cancer risk to consumers. In this report, the focus is on two types of DBPs, trihalomethanes (THMs) and haloacetic acids (HAAs). The cancer risks associated with DBPs are analyzed through ingestion and inhalation pathways. Ingestion and inhalation consist of common water uses like drinking, cooking, or bathing. In addition to this, DBPs have been shown to increase …

Trihalomethane (THM) detection in water is important due to the potential health effects caused by their presence, including increased cancer risk. A cheap, quick, and portable method of identifying THM concentration at the Environmental Protection Agency limit of 80 parts per billion (ppb) will improve detection and water treatment. Electrospinning was used to make nanofiber membranes using a 2.6 wt% polypropylene solution. These membranes were utilized in the Fujiwara reaction, which creates a color change in the presence of THMs, to detect the THM bromoform in water. The color intensity of the reaction was quantified for 250 and 80 ppb …
An Assessment Of Trihalomethanes And Haloacetic Acids On The Cancer Exposure Risk Of Ohio Drinking Water Systems, Stephen Sykes
An Assessment Of Trihalomethanes And Haloacetic Acids On The Cancer Exposure Risk Of Ohio Drinking Water Systems, Stephen Sykes

The cancer exposure risk from drinking chlorine-based disinfection by-products (DBPs) such as trihalomethanes (THMs) and haloacetic acids (HAAs) has been established as a major concern to public health as 98% of the United States drinking water systems in operation use chlorinated systems to disinfect the water they provide [2]. Using data collected from the Ohio Environmental Protection Agency from January 2014 to September 2017 in the cites of Cleveland, Columbus, Cincinnati, Canton, and Akron this study attempts to look at the risk of cancer caused by the DBPs. To show the relative risk of several different systems in operation from …
